Readings for Week 13
1. Web Search Engines:
This article is about the evolution of the search engine and how google, yahoo etc. search through millions of information and data constantly. This article discusses how web search engines are able to search through all of this data. They ignore a lot of low value data and there are a lot of confidential pages on the web that they cannot search. This would weed out a lot of stuff but there is still a lot of information on the web. Crawlers have a lot to decode and sort through so they often crash or burn out
2. Current Developments and Future Trends for the OAI protocol
OAI stands for Open Archives Initiative. It is used to create access for e-print articles but as expanded to other communities. This article was very repetitive. I got that the OAI did something with metadata and data harvesting but beyond that, I really didn't get it. This is another article that dropped a lot of big words but didn't really say much, at least for me.
3. The Deep Web: Surfacing Hidden Value
This article goes into the expansiveness of the web and how search engines very often just skim the surface of what's available. It seems very crazy that there is so much on the web that we never see. I just picture in the dark corners of the web, there's a balrog or two lurking or one of those fishes with lights hanging off of it's head. At first it seems like a really good idea to explore that unknown expanse of information but if it's not important or useful, is it really that imperative that we find it? We have information overload already (I experience this feeling everyday) and I don't really feel like adding to it.
